可再生能源消费对二氧化碳排放影响的统计检验

Statistical Test of Impact of Renewable Energy Consumption on Carbon Dioxide Emission

文章运用Hansen(1999)面板门槛模型,在考虑金融发展水平差异的情况下,考察了1994-2016年33个发达国家可再生能源消费和二氧化碳排放间的非线性关系。结果表明,可再生能源消费对二氧化碳排放的影响存在基于金融发展的显著双门槛效应;当金融发展水平较低时,可再生能源消费对二氧化碳排放的影响为正;当金融发展水平处于中等或者较高水平时,可再生能源的消费可以减少二氧化碳的排放,且随着金融发展水平的提高,二氧化碳排放的可再生能源消费弹性不断增大。

Taking into account the differences of financial development levels,this paper uses Hansen panel threshold model to investigate the nonlinear relationship between carbon dioxide emissions and renewable energy consumption in 33 developed countries from 1994 to 2016. The results show that the impact of renewable energy consumption on carbon dioxide emissions has a significant double threshold effect based on financial development;when financial development is at medium or high levels, renewable energy consumption can reduce carbon dioxide emissions, and with the improvement of financial development level, the elasticity of renewable energy consumption of carbon dioxide emissions increases constantly.
